Ahhhh, The Deck height changed from the original 20r (1975-1980) and 22r(1981-1984) to the 22R/RE from 1985-1995.
20R and the 22R blocks up to 1984 are the exact same except for the bore. Then in 1985 Toyota changed the deck height effectively lowering it and changing the piston wrist pin height on the pistons to accommodate. All 20/22R and 22RE's have the same crank and connecting rods.
See differences here:
20/22R timing guides up to 85 on DE-decked 22RE
Thats a 22RE Timing cover on a pre 85 block
